The invention concerns a magnetodynamic motor (1) with a static element or stator and a dynamic element, preferably a rotor or element rotating about an axis. To this effect, exciter magnets (2; 24; 45; 56) with a pole surface gap or air gap (10; 27; 37) are provided on the one element; on the other element, electrical drive elements for producing torque are provided. With respect to their transverse dimensions, the drive elements are nearly iron-free, long wire bobbins (5; 21; 34; 43; 55). In the air gap, the field of the exciter magnets (2; 24; 45; 56) overlays the polar fields at the ends of the wire bobbins (5; 21; 34; 43; 55). Moreover, the polar axis (r) of the exciter magnets (2; 24; 45; 56) and the magnetic axes of the wire bobbins (5; 21; 34; 43; 55) are nearly normal to each other. At least one end (p) of the wire bobbin runs through the air gap (10; 27; 37) of an exciter magnet (2; 24; 45; 56) between the middle of the air gap (10; 27; 37) and a pole surface and a contol element is provided which changes the polarity of the wire bobbins at the point of passage through the pole. |
